Kinetics of nitrogen absorption and desorption by melts of the Fe–C system with surface and volumetric oxidation in a stream of oxygen containing 0.2% of nitrogen with an initial metal temperature of 1350–1600°С, [С] = 0.8–3.8%, oxygen flow 0.24–1.8 liter/(minŊkg), are studied. It is established that there is excess chemical potential of nitrogen in a boundary layer compared with the nitrogen content in a gas stream.
